DOUBLE-PIN socnm.

. Application fi1ed March 7,1927. SerialNoxi7;3Q2.

' The-Object Oftl1is invention is to adapt the looped or hnmped end ofthe double pointed pin of the Boden, King & Chapman Patent, No.1,604,801, granted October 26, 1926, for use as a socket member of asnap fastener, and especially when snch adaptation is de signed for useas a pin fastener for attaching covers to upholstered automobile parts.

The invention consiste in a double pointed pin of the type Inentioned,having its upper ends converged so as substantially to close the loopedportion and adapt snob looped portion for use as'a resilient soclt for(:0- operation xvith a non-resilient or rigid stud or liead to serve asa snap tastener; it being nnderstood tliat instead of using the loopedend itself as the resilient member, it may be used to support anattached res ilient socket, as I Will proceed now to explain and finallydaim.

In the accompanying drawing illustrating the invention, in the severalfigures of which like parts are similarly designated, Figure 1 is afront elevation; Fig. 2 is a rear eleva tion; Fig. 3 is a sideelevation, and Fig. 4 is a top plan view illnstrating one embodiment 01"the invention. Fig. 5 in a front elevation; Fig. 6 is a 1ear elevation,and Fig. 7 is a side elevation illustrating the use of a modified formof the pin of the Boden, King & Chapman patent above mentioned inconnection vvith an attached resilient socket member. Fig. 8 is a rearelevation, and Fig. 9 is a top plan view of the pin shown in Figs. 5. 6and 7 detached. Fig. 10 is a rear elevation illnstrating a preferredmanner of uniting the pin and an attached socket.

Referring to the construction illn3trated in Figs. 1 t0 4 inclusive, thepin shown is of the double pointed variety, having the limbe 1 providedwith pointed ends 2, a looped head or end 3 having the humped portions4. and the bend 5. Difering from the pin of the Boden, King & Chapmanpatent mentioned, our pin has the hnmped portions 4 bent tovvard eachother or converged, so as to close that end of the pin snfiiciently t0prevent the escape of the stnd or head member. As Will be understood,the looped end is used as the socket member of the fastener, and it hassnficient resilience t-o permit yield t0 admit the stnd or head memberand when itis entered to snap back into secure engagement Withthe=studorheadnirfiber, and also t0 permit the forcible withdrawal of the stud orhead member when necessary or desirable.

The pin described may be utilized to support an attached resilientsocket member, as shown in Figs. 5 t0 7 and 10 inclusive. The socketmember referred to and herein designated 6, is of the mushroom orcollapsible type, slitted longitudinally, and having a stud orhead-engaging portion 7, with surrounding base or fiange elements 8, andthe crown elen1ent 9, the base and the crown elements being slittedlongitudinally to aitord resilience, and to permit of the mushrooming orcollapsing in order to secre the socket member to the pin. The pin, asbefore, has the limbs 1 pointed at 2, but the 100p end 10 issnbstantially circular t0 conform to the circnlar character of thesocket member. The humps 11 are bent inwardly so as more fully toencircle the socket member and secure its retention on the pin.

As already indicated, the soket member i s mushroomed or collapsed insetting, and in order to facilitate the application of the .settingtools thereto the pin -is applied to the socket member before it ishumped, as indicated in Fig. 10, and then the pin is hnrhped asindicated in Figs. 5 to 9, and the article thns finished.

WVhile the resilience of the pin may not be necessarily exerted in thatform of the in vent-ion in vvhich the sOcket membr is attached, still itis obvious that undue strains may be compensated for by the resilienceof the pin.

The invention is not limited to the use of the particular form ofresilient socket mem ber herein shown; and it is possible also tosubst1tute a non-reS1l1ent socket member for the resilient socketmember; and other variations in the details of' the construction arepermissible within the principle of the invention and the claimsfollowing.

VVhat we claim is:

1. A double pin socket, for use as a member of a snap fastener,comprislng a double ber of a snap fastener, comprising a .d0ub1e berof'a snap fastener, comprising a double pointed pin having a loopedandhmped pointed pin having a, looped and humped end, combined with anadded socket member and, the humps bent inwardly, combined embraced andheld by the looped end of the with an added socket member embraced and 1in. he1d by the looped and of thepin between 3. A double pin socket,comprising a the humps. double pointed pin having a looped and, and Intestimony whereof we have hereunto a socket member mushroomed orCollapsed set our hands this 4th day 01 March, A. D. within said loopede nd t0 efi"ect a union of 1927. 1 the pin and socket member. PAUL E.FENT ON.
